RADIATOR.

Patented May 15, 1917.

Original applicatiqn filed December 6,1915, Serial No. 65,265. Divided and this application filed March 21, 1916. Serial No. 85,5 =7.

To all whom it may concern:

Be it known that I, GEORGE W. TURNEY, a citizen of-the United States, residing at Rome, Oneida county, State of New York, have invented certain new and useful Improvements in Radiators,'.the following being a full, clear, one form of my invention which I at present deem preferable. 4

For a detailed description of the present form of my invention, reference may be had to the following specification and to-the accompanying drawing, which illustrates my invention, wherein' Figure 1 shows vthe helical flange in its original form, and

tljig. 2 shows the flange applied to the tu e.

My invention relates to a radiator such as is'used in automobiles, and involves a radiator-tube having a helical flange thereon .thi description;

in the form of a separate helix of edgewise wound copper secured" to the outside of the tube by means of a line of solder extending longitudinally between the tube and the flange, In my application of December 6th, 1915, SerialNumber 65,265, of whichthis application is a division, I have claimed a method of manufacturing a radiator-tube of I ,intend to claim herein the radiator-tube itself.

Referringto the drawing,

\ A represents the flange as it is originally formed, being wound edgewise. B is the tube on wh' h the coiled flange is placed'and the convo utions distended as shown in Fig. 2, to the desired'extent. The flange is then secured in its distended condition to the tube by means of a longitudinal cord of solder C laid in a and exact disclosure of the resilient metallic ribbonrecessbetween the tube and the inner per phery of the flange. In this case the recess is formed in the successive turns of the flange as indicated at a. The parts be- .thereon in their spaced relation 'as shown.

It will be understood that the distention of the helix causes the several convolutions thereof to tightly grip the tube, so that the chief efl'ect of the solder is to keep the convolutions spaced apart in their tube-gripping relation.

What I claim as new and desire to secure by Letters Patent is:

1. An improvement in radiators comprising a tube, a closed annular helix of resilient metallic ribbon coiled edgewise, each convolution having a recess in its inner periphery, the convolutions of said ribbon being distended along the tube, and a solder thread contained in said recesses and attaching said convolutions to said tube.

2. An improvement in radiators comprising a tube, a closed annular helix of resilient metallic ribbon coiled edgewise, each convolution having a recess 1n its inner periphery, said recesses being in alinement of said ribbon being distended along the tube, and a solder thread contained in said recesses and attaching said convolutions to said tube.

In witness whereof I have hereunto set my hand, this 17th day of March, 1916.

' GEORGE'W. TURNEY.
